Spell check suggestions offset vertically when page is scrolled

Description

When the Spell Check feature of TinyMCE is activated, and the current page is scrolled down, the pop-up box that displays the spelling suggestions is moved UP in proportion to how far down the page is scrolled. This could potentially lead to the spelling suggestions being displayed above the browser view, making it seem as if this functionality is not working at all.

I have found this to be reproducible on the following browsers: IE 9.0.3, Firefox 7.0.1, Safari 5.1.1 on Windows 7, and Firefox 7.0.1 on Linux Mint (Ubuntu based). This occurs with no active plugins, and when using the Twenty Eleven theme, so I do not believe it is caused by a plugin or theme.

It looks like this was from back in April 2011. I admit that I am not terribly familiar with the guts of TinyMCE, so if the answer to this question is easily found, please forgive me: What version of TinyMCE is WordPress using?

I am also seeing that the proposed fix you mention seems to have not been implemented yet (as best as I can tell) in the TinyMCE master branch on GitHub. Is anyone familiar enough with submitting fixes to TinyMCE to submit that fix to them?

Yes, there is a newer release of the spellchecker plugin for TinyMCE (2.0.6) where that is fixed. It's a bit late for updated external libraries but since this is only a plugin with seemingly minimal changes, perhaps we can test it fast and include it in 3.3.

For testing you can download version 2.0.6 of the spellchecker plugin and replace the old one in wp-includes/js/tinymce/plugins on a test install (I'll be doing that too). Then have a look in as many different browsers as you can to confirm all is working okay.
